Abstract
The utility model provides a supporting device for a space grid in a large tower. The large tower is internally provided with a foundation beam; the surface of the foundation beam is distributed with upright posts at intervals; X-directional crossbeams and Y-directional crossbeams are arranged in layers and horizontally supported among the upright posts and between each peripheral upright post and a tower body; and in-tower functional pieces are horizontally supported by each layer of X-directional crossbeams and Y-directional crossbeams respectively. The device consists of a foundation beam, all the upright posts, the X-directional crossbeams and the Y-directional crossbeams and has the characteristics of large strength, good rigidity and small flexibility; and particularly, the existing long crossbeam with large span is divided into the short crossbeams with small spans by a multi-upright post structure; therefore, the high levelness of a tower disc can be ensured. The device has strong capability of resisting the impact force of high-speed variable-gas load, can effectively avoid vibration accidents due to impact; and particularly a baffle plate of the structure is divided into sections, thus avoiding resonance due to impact, and further ensuring long-term stable run of the tower. The supporting device has the outstanding advantages of reducing the manufacturing and mounting difficulty and reducing investment.
